EarthMoving Equipment Tyres
OTR Tyres for all Earthmoving and Agricultural machinary
Large Range of Tyres available
BIAS, RADIAL & SOLID RUBBER TYRES
Earthmoving Tyres
Earthmoving tyres, (Off-the-road – OTR tyres) are specifically designed for use under extreme conditions in rough terrains or terrain where traction, durability, reliability are required, including construction sites, mining and quarrying, and other industrial environments like recycling plants, logistics and warehousing environments. Alliance OTR tyres are available the World Over and respected as Tyres of Quality and Durability, manufactured for specific machinery types and working conditions.
Alliance Earthmoving tyres come in various types, each tailored to different conditions and equipment requirements.
Types of Off-The-Road (OTR) tyres for Earthmoving Equipment
Bias (Diagonal) Ply tyres
Tyre Construction
Layers of rubber-coated fabric are placed diagonally across each other. The layers crisscross one another, forming a pattern that gives the tyre its structural integrity and strength and providing consistent strength throughout the tyre. The crisscross pattern provides thicker and stronger sidewalls, making bias ply tires highly resistant to cuts, punctures, and damage from rough and rocky terrain. This construction is particularly beneficial in environments where sharp objects and debris are common, such as construction sites, mining operations, and demolition areas.
OTR Bias Tyres Characteristics
Strong sidewalls.
Greater resistance to punctures.
Less heat resistance compared to radial tyres.
Distribute the weight evenly across the tyre.
Ability to support substantial weights without deforming, which is crucial for heavy machinery and earthmoving equipment.
The bias design allows the tire to flex more, providing better grip on uneven and loose surfaces.
OTR Bias tyres have a lower Initial Cost as they are generally less expensive to manufacture than radial tires. They are also easier to repair, which can reduce maintenance costs over their lifespan.
Common use cases
Suitable for rough terrains with a high risk of cuts and punctures, such as construction and demolition sites. Any site or quarry where loose rock, steel reinforcing bars or similar sharp objects are prevalent on the site.
Earthmoving equipment that typically uses Bias Ply Tyres
Bulldozers
Bulldozers benefit from the strong sidewalls of bias ply tyres , which offer resistance to the cuts and punctures typical in heavy construction and demolition work.
Loaders
Often used in rugged environments, loaders need the durability and puncture resistance provided by bias ply tyres .
Scrapers
Bias ply tyres can withstand the rough conditions and sharp debris often encountered in mining and large-scale earthmoving projects.
Radial Earthmoving tyres
Tyre Construction
Layers of fabric are placed perpendicularly to the direction of travel, with steel belts running around the circumference. This type of construction offers better durability than OTR Bias Tyres. Radial tyres have better heat dissipation due to their construction, reducing the risk of overheating and improving tread life. Radial construction leads to more uniform wear and a longer overall lifespan. The flexible tread allows for excellent contact with the ground which in turn enhances traction and stability. Radial tyres are particularly effective at higher speeds and during cornering making them the natural choice for ADT’s. Motor graders and Tractor loader Backhoes (TLB).
Radial OTR Tyre Characteristics
Greater flexibility
Better heat dissipation
Longer tread life
Improved fuel efficiency
Common Uses of Radial OTR tyres
Ideal for longer distances and higher speeds on smoother surfaces, such as highways or hard-packed dirt roads, quarries and open cast mines.

Articulated Dump Trucks (ADTs)
Radial ply tyres are preferred for their ability to handle higher speeds and longer distances, providing better fuel efficiency and comfort.
Motor Graders
These machines, used for road construction and maintenance, benefit from the smoother ride and longer tread life of radial tyres .
TLB (Tractor Loader Backhoe)
For backhoes that frequently travel on paved or hard-packed surfaces, radial tyres offer improved performance and longevity.
Solid rubber tyres
Sild rubber tyre Construction
Made entirely of rubber or a blend of rubber and other materials. Solid rubber tires come in various tread patterns designed for different surfaces and applications but are most often associated with Forklift tyres. There are both marking and non-marking rubber compounds used to produce specific tyres and patterns for the individual application. While the initial cost may be higher than pneumatic tires, the extended lifespan and reduced maintenance needs often result in lower total cost of ownership. The durability and low maintenance of solid rubber tyres contribute to fewer interruptions in operations, enhancing productivity.
Solid Rubber Characteristics
Completely puncture-proof
Extremely durable
Heavier, which can impact fuel efficiency
Smooth ride on hard surfaces
Consistent stable performance
Common Uses of Solid Rubber tyres
Suitable for environments with a high risk of tire damage, such as scrapyards or recycling plants.

Forklifts
Often used in warehouses and scrapyards, forklifts benefit from the puncture-proof nature of solid tyres .
Skid Steer Loaders
In environments like construction sites or recycling facilities, where sharp objects can cause frequent punctures, solid tyres ensure uninterrupted operation.
Telehandlers
Telehandlers are extremely versatile machines used in construction and agriculture that often operate in rough conditions where solid tyres provide durability and stability. Telehandlers, depending on their application and terrain also use radial tyres.
Importance of Using the Correct tyres for Earthmoving Equipment
Safety
Using the appropriate tyres reduces the risk of tire failure, which can lead to accidents and injuries. Proper traction and stability are crucial for maintaining control of heavy machinery.
Efficiency
The right tyres can significantly enhance the performance of earthmoving equipment by improving fuel efficiency and reducing the wear and tear on the vehicle.
Durability
Choosing tyres that match the working conditions extends the lifespan of the tyres , reducing the frequency of replacements and downtime. For example, solid or foam-filled tyres are preferable in environments with sharp debris to prevent frequent punctures.
Cost-Effectiveness
While the initial investment in the right type of tire might be higher, it leads to cost savings in the long run due to fewer replacements, less downtime, and improved fuel efficiency.
Productivity
tyres that provide better traction and stability enable machinery to operate more effectively, increasing overall productivity. For instance, radial tyres offer a smoother ride and better fuel economy for equipment that travels long distances.
Machine Longevity
Correct tire selection minimizes the stress on the vehicle’s suspension and other components, thereby prolonging the life of the equipment.
